ABSTRACT:
A dielectric filter is formed of resonators connected in series with dielectric coupling windows disposed therebetween. When the dielectric constant of the dielectrics which form the dielectric coupling windows is made different from that of the dielectrics which form the resonators, dielectric filter having the same central frequency and a different pass-band width is obtained without changing the shape and dimensions of the dielectric coupling windows.
